Expand description

Compute functions can ask arrays for compute kernels for a given invocation.

The kernel is invoked with the input arguments and options, and can return None if it is unable to compute the result for the given inputs due to missing implementation logic. For example, if kernel doesn’t support the LTE operator. By returning None, the kernel is indicating that it cannot compute the result for the given inputs, and another kernel should be tried. Not that the given inputs are invalid for the compute function.

If the kernel fails to compute a result, it should return a Some with the error.

Required Methods§
